Maybe it was the mass utterance of "...eh?" by the online community since its reveal, maybe it was the hands-on impressions at CES, but for whatever reason Valve's Steam Controller is undergoing a redesign for the more conventional. Information from the Steam Dev Days developer conference in Seattle indicates that the next version of the gamepad in what Valve has emphasized is its beta period will nix the center touch screen for a more traditional button layout.
Valve also stated that the controller should expect to undergo further changes before it makes its way to retail, but a few more concrete details have surfaced: the Steam Controller will run on AA batteries, machines will support up to 16 players using the controllers simultaneously, and the controller is being developed "with VR in mind." Oculus Rift compatibility perhaps?
